disturbance, on the west side of the mine entrance road, the silt fence also was not long enough, and <br />sediment laden water flowed around it. The silt fence below the pond was not allowing sediment to <br />leave the site, but should nonetheless be reinstalled, because it was not properly trenched. The <br />material piled on top of the silt fence bottom will likely erode, leaving an opening between the fence <br />and the ground surface. <br />An interim/construction phase collection ditch was in place below the topsoil stockpile, to prevent <br />sediment and erosion on the undisturbed downslope area. A low area in the ditch was holding water. <br />If it is BRL's intention for runoff from the stockpile to be carried to an impoundment, the impoundment <br />would be subject to the requirements of Section 4.05.9. If the water is to be discharged, BRL should <br />take necessary precautions (silt fence, straw babes, rock check dam, etc.) to ensure that excessive <br />erosion and sedimentation do not occur in the undisturbed area below the stockpile. <br />BAL needs to ensure that all drainage and sediment control features such as ditches and berms <br />depicted on Map No. 20 are installed and maintained. It is also imperative that sediment is controlled <br />at all areas of the mine site, with all sediment retained on the disturbed area. If silt fences prove <br />ineffective, then alternate measures must be taken. BRL needs to provide a revised plan which <br />incorporates the new sediment control features and provides an other measures needed to ensure <br />that sediment is retained on disturbed areas, and that disturbed areas are not subject to sediment <br />yield and or erosion. <br />
